Magnetoresistance peculiarities and magnetization of materials with two kinds of superconducting inclusions


Low-temperature properties of a crystal containing type I superconducting inclusions of two different materials have been studied. In the approximation assuming that the inclusions size is much smaller than the coherence length/penetration depth of the magnetic field, the theory of magnetoresistance of a crystal containing spherical superconducting inclusions of two different materials has been developed, and magnetization of crystals has been calculated. The obtained results can be used for correct explanation of the low temperature conductivity in binary and more complex semiconductors, in which precipitation of the superconducting phase is possible during the technological processing or under external impact.

Effect Y substitution on the microstructure, transport and magnetic proprieties of Bi2Sr2Ca1Cu2O8+δ superconducting ceramics

1 Introduction In high Tc superconducting (HTSC) materials the main parameter for practical applications is, beside the critical temperature of transition Tc, the critical current density. This parameter, which limits the transport of current carried by the material, is controlled by the capability of pinning vortices under applied magnetic field. This is why activation energy, or pinning potential, was studied earlier in Bi based high Tc superconducting materials (HTSC) in both single crystals [ 1 - 3 ] and polycrystalline [ 4 , 5 ] samples. The pinning
